The Quick Read: It depends on what happens to the HELOC. Either the new first mortgage pays the line off at closing, or the line stays open behind the new loan and its lender agrees to sit second. Each path triggers different rules, so the best program for your situation follows from that choice, not the other way around. Conventional cash-out is the usual route when the HELOC has to go, and the FHA and VA streamlines generally can’t pay one off.
Key Takeaways
- A HELOC is a second mortgage. It affects every refinance of the first loan.
- Paying off a HELOC that did not buy the home makes the new loan a cash-out refinance.
- Keeping the HELOC means its lender must agree to stay in second position, and that lender can say no.
- Combined leverage counts the HELOC’s full credit limit, not only what you’ve drawn.
- Any HELOC payment that remains goes into your debt-to-income ratio.
Key Terms Defined
Cash-out refinance: A new first mortgage that pays off the old one and pays you the extra equity in cash.
HELOC: A home equity line of credit, a revolving second mortgage secured by the home.
Subordination: A signed agreement where the HELOC lender agrees its lien stays behind the new first mortgage.
CLTV / HCLTV: Combined loan-to-value. The HCLTV version counts the HELOC’s full credit limit.
Seasoning: How long you have owned the home or held the loan being paid off.
Limited cash-out (rate-and-term) refinance: A refinance that pays off the old loan and costs, with only incidental cash back.
Cash-out refinance estimate
The starting figures are an example value with a balance and a cash request in proportion. Replace them with yours.
Editable benchmark: 7.24% as of October 29, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a cash-out refinance quote.
Illustrative starting assumptions: a $350,000 home value, a $193,000 current balance, the agency cap on a one-unit principal residence, a thirty-year term at the current Freddie Mac benchmark, and property taxes and insurance estimated at typical national rates. Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a cash-out refinance quote; a cash-out loan is priced by the lender at lock. The cash available is the loan the program cap allows less the balances paid off, before closing costs, which are not included. The HELOC line is the program’s combined loan-to-value ceiling applied to the same value and balance. Taxes and insurance are editable estimates. Licensed in sixteen states for consumer mortgages.
What Does an Open HELOC Do to a Cash-Out Refinance?
An open HELOC adds a second lien that has to be dealt with at closing. The federal consumer-finance regulator explains that you may need the HELOC lender’s approval to refinance your first mortgage. That lender can refuse. If it does, you may have to pay the HELOC off to move forward.
So the file has two moving parts, not one. The new first mortgage has to meet its own program rules. The HELOC has to be paid off or pushed into second place.
Across the wholesale programs Lendmire places files with, this is where files stall. Not on credit. Not on income. On a HELOC lender who hasn’t answered a subordination request, or a payoff letter that shows a balance nobody expected.
The Two Paths: Pay It Off or Keep It
Path A: pay the HELOC off at closing. The new first mortgage is bigger. Part of the proceeds retires the line. The line closes, so no subordination is needed. The tradeoff is that you lose the revolving access.
Path B: keep the HELOC open. The HELOC lender signs a subordination agreement so the new first mortgage takes first position. You keep the line and the second payment. Fannie Mae’s subordinate financing rule requires a recorded resubordination agreement when a lender leaves subordinate financing in place. The exception is where state law lets the lien keep its position.
| Factor | Path A: Pay off | Path B: Keep open |
|---|---|---|
| Who must approve | New first lender | New lender plus HELOC lender |
| Net cash to you | Reduced by payoff | Not reduced by the line |
| Payments after | One | Two, if the line is drawn |
| Main risk | Lose revolving access | HELOC lender refuses |
| Fits when | You want one loan | You want the line kept |
Does Paying Off the HELOC Make It a Cash-Out Refinance?
Usually yes. This is the most misunderstood rule on these files.
Fannie Mae’s limited cash-out guidelines let the new loan pay off a subordinate lien only if it was used to buy the property. The lender has to document that all of the proceeds funded part of the purchase price. A HELOC drawn for a kitchen, a car or debt payoff doesn’t qualify. Pay that line off and the loan is cash-out.
Two exceptions come up. A HELOC sitting in first-lien position, with no other mortgage on the home, is treated as part of the first mortgage being refinanced. And certain disaster-repair draws can be consolidated under limited cash-out flexibilities.
Cash-out brings its own rules. On a conventional loan the leverage cap is 80% LTV on a one-unit principal residence and 75% on two- to four-unit principal residences. The mortgage being paid off must be at least 12 months old, counted note date to note date, and at least one borrower must have been on title for 6 months. Delayed financing, inheritance and legal-award exceptions exist. All of this is subject to lender guidelines and full file review.
How a Cash-Out With a HELOC Is Underwritten, Step by Step
1. Pull the HELOC facts. Get the credit limit, the drawn balance, whether a payment is required, the lien position, and what the draws paid for. If any of it bought the home, you’ll need paperwork proving it.
2. Classify the loan. HELOC paid off and not purchase-money means cash-out. HELOC left open means the loan can still be limited cash-out or rate-and-term, but it needs resubordination.
3. Pick the path. Pay off, or keep and subordinate. This decision drives the rest of the file.
4. Review credit, income and DTI. Under Fannie Mae’s debt rules, a HELOC that stays and requires a payment, principal-and-interest or interest-only, counts in monthly debt. A line with no required payment adds no recurring obligation. The wholesale conventional programs start at a 620 decision score, and the automated finding governs most files, with a total ratio ceiling of 50%.
5. Test combined leverage. The lender looks at the new first loan plus the HELOC together. The HCLTV figure counts the HELOC’s full credit limit, not just what you’ve drawn. Fannie Mae’s Eligibility Matrix sets maximum LTV, CLTV and HCLTV for a primary residence with subordinate financing.
6. Appraisal. The value feeds every leverage test. The appraiser must be told about the subordinate financing.
7. Collect documents. Payoff letters for the first mortgage and any HELOC. A subordination request to the HELOC lender if the line stays. Title work. Proof of how any subordinate loan was used.
8. Close and clean up. Liens are paid in priority order. If the HELOC is paid off, get a signed close-account request and a lien release. A line left technically open can be drawn again after closing. That’s practical file advice, not a program rule.
Why a Zero-Balance HELOC Still Matters
An unused line is not invisible. The lien exists. The credit limit still counts toward HCLTV, so it eats into the equity a cash-out can reach. With no required payment, it adds nothing to DTI. But the HELOC lender still has to subordinate if the line stays.
Picture a homeowner who opened a line years ago and never touched it. They assume it’s irrelevant. The lender asks for a subordination agreement or a payoff and closure letter anyway. That surprise is avoidable by raising the line on the first call.
Where the General Rule Breaks
- First-lien HELOC. If the HELOC is the only mortgage, paying it off is treated differently than paying off a second lien. Fannie Mae’s limited cash-out guidelines treat a first-lien HELOC as part of the first mortgage being refinanced. Freddie Mac also carves out first-lien HELOCs in its seasoning rules, so confirm the current treatment with the lender.
- Purchase-money HELOC. Rolled in without becoming cash-out, but only with documentation.
- State law. In some states the HELOC keeps its position without resubordination.
- Variable-payment seconds. Allowed on subordinate financing when specific provisions are met.
- Texas homesteads. A cash-out on a homestead (a Section 50(a)(6) loan) is capped at 80% of the home’s value by the state constitution, and the wholesale 89.99% lane is not written there.
- Recently opened lines. A HELOC opened shortly before applying can complicate the file, and a recent draw can be a problem if the funds were not used for the purchase and the documentation does not show where they went.
Which Program Fits Which Borrower?
The best program for your situation depends on the loan you hold today, how much equity you need, and what you want to do with the line. A mortgage broker shops several wholesale lenders and matches the scenario to the program. Lendmire’s cash-out refinance programs page lays out that range.
| Borrower situation | Likely lane | HELOC handling | Watch-out |
|---|---|---|---|
| Needs cash, HELOC can go | Conventional cash-out, 80% LTV one-unit | Paid at closing | Payoff shrinks net cash |
| Wants cash and the line kept | Conventional cash-out | Subordinate | HELOC lender may refuse |
| HELOC bought the home, no cash needed | Rate-and-term, up to 95% LTV | Roll in with proof | Documentation |
| Existing FHA loan, no cash needed | FHA Streamline | Must be resubordinated | Can’t pay off a HELOC |
| Existing VA loan, no cash needed | VA IRRRL | Must be resubordinated | Can’t pay off other liens |
| Strong score, conforming balance, primary home | Wholesale lane to 89.99% LTV, no MI | Paid off | 680 score, 50% ratio, 6 months seasoning |
A few notes on that table. The FHA and VA streamlines refinance only the existing government loan, so if the HELOC must go, a cash-out product is the route. The VA IRRRL carries a 0.5% funding fee unless exempt and a seasoning requirement of the later of 210 days and 6 payments. The FHA Streamline needs a net tangible benefit. Loans above the conforming limit move to the jumbo lanes, which start at a 660 decision score, reach 90% leverage and run to $5,000,000, with a 50% ratio ceiling on the fixed lanes. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Mortgage insurance applies above 80% LTV on the agency path, with the wholesale no-MI cash-out lane as the exception. It can be cancelled on request at 80% of original value with good payment history and no subordinate liens, and it must end automatically at 78%. Note the wrinkle: a HELOC left in place is a subordinate lien, which can block that cancellation request. All figures are subject to lender guidelines.
Does the HELOC Lender Have to Agree?
If the line stays, yes. Subordination changes lien priority only. It doesn’t change the HELOC’s terms. But the HELOC lender has no obligation to sign.
When it refuses, the borrower has three fallbacks:
1. Pay down or pay off the HELOC with savings and close the line.
2. Roll the payoff into a cash-out refinance, accepting the reduced net cash.
3. Wait and revisit, since combined leverage may look better after a paydown or a value change.
Never close without the subordination in hand. A closing that leaves the HELOC ahead of the new loan doesn’t fit any program’s lien-position requirement, and the title work won’t clear.
The Money Side: Two Payments or One
Paying the HELOC off folds it into one loan, but the entire first mortgage resets to new terms. That’s the real cost. You give up your old loan’s remaining term on the whole balance, not only on the new money. Cash-out pricing adjustments apply to the full loan, and the Fannie Mae Selling Guide’s cash-out refinance section states that cash-out pricing applies to these transactions.
Keeping the HELOC means two payments, and a required HELOC payment counts against DTI. It also leaves you with a variable-cost line next to a fixed first mortgage. Some borrowers want exactly that. Others find it’s one obligation too many.
Run it as a decision, not a formula. Compare what you keep (the existing first mortgage terms, the line’s access) with what you gain (cash, one payment, a cleaner structure). Closing costs on a cash-out and any subordination processing apply either way, and a Loan Estimate will show them before you commit.
Why Do Sources Disagree About Doing Both?
You’ll read “you can’t do both,” “not for the same equity,” and “some lenders allow it.” All three are partly right. You can’t do a cash-out that pays off the HELOC and keep the HELOC. You can do a cash-out and keep the HELOC if its lender subordinates and combined leverage fits. And a lender’s overlays can be tighter than agency minimums. The answer comes down to which path, which lender, and the numbers.
What to Ask and Bring Before You Apply
- The HELOC credit limit, drawn balance and payment terms.
- Whether any draws paid for the purchase of the home.
- The HELOC lender’s subordination process, and who handles it.
- A payoff statement for each lien.
- Your reason for keeping the line, if you are.
- Home age, ownership history and the date of the current first mortgage, for seasoning.
Frequently Asked Questions
Can I do a cash-out refinance while I still have a HELOC?
Yes, in two ways. The proceeds can pay the HELOC off, or the HELOC stays and its lender subordinates to the new first mortgage. The HELOC lender has the final say on the second path, and combined leverage must fit the program.
Is paying off my HELOC a rate-and-term refinance?
Only if the HELOC was purchase-money and you can document it. If any of it funded something other than the purchase, the loan is cash-out and the cash-out leverage and seasoning rules apply.
Does a HELOC with a zero balance matter?
Yes. It adds no payment to your DTI, but the lien still needs to be subordinated or closed, and its full credit limit counts toward combined leverage.
Can an FHA Streamline or VA IRRRL pay off a HELOC?
Generally no. Both are limited to the existing government loan. If the HELOC must be paid off, a cash-out product is the route, and if the line stays, its lender must subordinate.
What if my HELOC lender refuses to subordinate?
You can pay the line off with savings, roll the payoff into a cash-out refinance, or wait and try again after a paydown. Don’t close without the agreement.
